If you empty it out and fill it with capacitors, it will hold a few
megafarads at 2 volts.
Erm... I doubt this. I saw a 2 farad cap at a surplus place in Lima,
Ohio. It was rated at 12 volts, and looked like a sawed-off oil drum.
I think there's some sort of square-cube thing going on here that makes
ever-increasing values of capacitance ever huger.
You can buy 10F 15V capacitors in car audio shops. They're about the
size of a beer can (a normal UK/EU 500ml can, not a dinky little US
330ml can).
